In prior work with Bregman and Vogtmann, we constructed an analogue of “Outer Space” for right-angled Artin groups. In this talk, I will review the construction of this space, then discuss more recent work in which we show that any finite subgroup of the (untwisted) outer automorphism group, fixes a point in this Outer Space.
